mariadb-slap & mysqlslap for MariaDB Enterprise Server 10.3

The mysqlslap utility is used to emulate client load and perform diagnostics with MariaDB Enterprise Server 10.3. It operates as though multiple clients were accessing the server.

MariaDB Enterprise Server 10.3 does not provide a symbolic link to the utility's new name (mariadb-slap), so the legacy name must be used.
